choice of hydraulic double plunger continuous screen changer series

The selection of a new type of screen changer filter should be selected based on several factors such as materials, product types, production volume, material pressure in the system, and degree of automation.

The general principle is: high product quality, high production efficiency, long production process, high degree of automation, choose non-stop continuous screen changer, can replace the filter without interrupting the product, increase production, save energy, easy to operate, and no waste.

The production process is short, the degree of automation is low, and the product quality requirements are not high. You can choose a fast non-stop screen changer. The quick screen changer saves time, is low in price and saves investment.

bolt-type continuous hydrauliic screen changers for extruder Main failures and causes: 

malfunction cause of issue elimination method
Too much leakage Screen changer bolts or front and rear flange connecting bolts are loose Lock
Setting the screen change pressure is too high Turn down
Filter block cannot be pushed Unreasonable installation, using sliding clearance changes Contact the manufacturer
There is debris in the filter slot or the filter is exposed and stuck in the slot It can be pulled back to exclude, otherwise it will be removed by disassembly
No lubricating oil makes the sliding surface bite Disassemble and repair
The oil pump is not oiling Motor reverse Adjust
The oil level is too low and the oil is too thick correct
The oil inlet pipe is not tightly sealed and leaks air seal
The oil pump is noisy Air leakage in the oil inlet Find the source of the leak
Clogged oil filter Clean up dirt
Pressure regulator failure The overflow port of the pressure valve is contaminated and blocked, and there is no oil pressure Clean with diesel
Reversing valve failure The valve core and valve port are blocked or damaged Clean or replace

Notes: The capacity will be affected by the fluidity, filter fineness and purity of materials.
